It was way nicer than a book.
That's the experience I'm speaking from. It wasn't perfect, and it was wrong sometimes, sure. A known limitation.
But it was flexible, and it was able to do things like relate ideas with programming languages I already knew. Adapt to my level of understanding. Skip stuff I didn't need.
Incorrect moments or not, the result was i learned something quickly and easily. That isn't what happened in the 90s.
